How to Install or Update Java
Java is a programming language originally developed by Sun Microsystems. It is widely used by developers of various Internet applications. Your Internet browser (Internet Explorer, FireFox, etc…) uses Java to perform many different functions. A problem with the Java installation on your computer is one possibility for experiencing various problems within Blackboard or other applications, such as:
- Internet browsers not functioning properly (this includes the Respondus Lockdown browser)
- Pages not loading properly
- Buttons or Menus not appearing or not functioning properly
- Test Timer not appearing
- Being “kicked out” or locked out of a test or quiz
- Being unable to post to the Discussion Board
- Being unable to submit an assignment
Note: The steps below may be somewhat difficult for beginning computer users. If you would like assistance with using these instructions, please contact the CTC HelpDesk.
Identifying the Version(s) of Java Installed on Your Computer
One way Windows users can find out what version of Java is installed is to open a Command prompt and enter a command, as follows: Click Start and then Run, enter cmd and then press Enter. At the Command prompt, type java -version and press Enter. Please note: If multiple versions of Java are installed, this will only display the most current version.
One way Macintosh users can find out what version of Java is installed is to open a Terminal window and enter a command, as follows: Open the Hard Drive (located on the Desktop); next, go into Applications, and then Utilities. (Another way to open Utilities is to hold down the following keys: Shift + Apple + U.) Next, double-click on Terminal. At the Command prompt, type java -version and press Return. Please note: If multiple versions of Java are installed, this will only display the most current version.
Because Java may be automatically updated when new versions are released, some computers will have multiple versions of Java installed; this can be a source of some problems. Windows users can check for multiple versions by going into Add/Remove Programs in the Control Panel. If multiple versions are found, we recommend uninstalling ALL instances of Java before installing the most current version. This will help insure that all Java components are updated properly when future automatic updates occur.
